There is increasing evidence that not all types of sedentary behavior have the same harmful effects on children's health. Hence, there has been a growing interest in the use of wearable cameras. The aim of this study is to develop a protocol to categorize children's wearable camera data into sedentary behavior components. ⋯ A reliable annotation protocol to categorize wearable camera data of children into sedentary behavior components was developed. Once applied to larger samples in children, this protocol can ultimately help to better understand the potential harms of screen time and sedentary behavior in children.

This study aims to identify the trends in incidence and prevalence of untreated caries in permanent teeth in China during 1993-2017. ⋯ The increased burden of untreated caries in China after 2010 is driven by those aged <25 years. Untreated caries data from the Global Burden of Disease study are a valid complement to the data from the Chinese National Oral Health Epidemiology Surveys.

This study examines the prevalence of risky cannabis use based on adherence to the Lower-Risk Cannabis Use Guidelines. ⋯ Lower-Risk Cannabis Use Guideline adherence differed by jurisdiction and sociodemographic profile. As more jurisdictions legalize nonmedical cannabis, targeted interventions for key risk behaviors (e.g., using high-potency cannabis, early initiation age, driving after cannabis use) are warranted.

This study seeks to describe the circumstances of fire deaths among children, identify deaths related to fireplay, and compare children whose deaths were related to fireplay with non-fireplay-related deaths. ⋯ This study provides data on supervision and the role of fireplay in fatal fires among young children, offering information for the development of innovative primary prevention strategies and future research.

In malaria-endemic countries, malaria during pregnancy is associated with adverse birth outcomes, including low birth weight (i.e., <2.5 kg). However, the effects of the widely promoted and recommended approaches of intermittent preventive treatment for malaria in pregnancy and insecticide-treated nets for pregnant women on low birth weight have been insufficiently examined. This analysis investigates the independent and combined effects of intermittent preventive treatment for malaria in pregnancy and insecticide-treated nets on low birth weight among Malawian children. ⋯ There were evident benefits of independent and combined use of intermittent preventive treatment for malaria in pregnancy and insecticide-treated nets on low birth weight, thereby supporting the use of these interventions during pregnancy. The reduced protective effects of intermittent preventive treatment for malaria in pregnancy over time highlight the need for innovative preventive methods against malaria in pregnancy.
